Quick answer
Loss run analysis before renewal helps identify cost drivers, correct claim errors, and present a cleaner risk profile to underwriters. This guide shows how to pull, review, and leverage loss runs for better renewal outcomes—without guarantees, but with stronger preparation.
What to pull from your loss runs
- 5-year claims summary: total incurred, paid, and reserves by policy year.
- Open reserves: any claims with remaining financial exposure.
- Claim types by frequency: pattern showing repeat incidents (slips/falls, auto, property).
- Loss ratio by policy: compare your losses to premium paid.
- Subrogation status: confirm whether carriers pursued recovery from third parties.
7-step loss run workflow before renewal
1. Request loss runs 90-120 days before renewal
Contact your current carrier or broker and request full loss runs for the past 5 years, including open and closed claims with incurred amounts. Early requests allow time for corrections or clarifications before underwriting begins.
2. Verify claim accuracy line by line
Review each claim for correct dates, amounts, and descriptions. Errors like inflated reserves, wrong policy numbers, or duplicate entries can artificially increase perceived risk. Document discrepancies and request corrected reports promptly.
3. Identify and close stale reserves
Look for claims with open reserves older than 24-36 months with no recent activity. Ask your carrier to evaluate whether reserves can be closed or reduced. Lingering open reserves signal ongoing exposure to underwriters.
4. Categorize claims by preventability
Separate claims into three buckets: preventable (training/process fixable), not preventable (true accidents/external), and frequency-driven (repeat incidents). This helps focus loss-control efforts where they matter most and shows proactive management.
5. Document post-loss corrective actions
For each significant claim, list what changed afterward—new safety protocols, equipment upgrades, training programs, or process changes. Underwriters respond better when they see concrete responses to loss patterns.
6. Build a one-page loss summary
Create a clean summary sheet showing 5-year loss history, closed vs. open, loss ratio by line, and key corrective actions. Bring this to broker meetings and renewal discussions to control the narrative around your risk profile.
7. Share proactively with competing carriers
When shopping quotes, provide your loss summary and corrected runs upfront. Transparency positions you as a well-managed account and can improve pricing or appetite from new carriers.
Common mistakes to avoid
- Waiting until renewal week: rushing limits your ability to correct errors or negotiate reserves.
- Ignoring small frequency claims: multiple small losses signal poor loss control even if severity is low.
- Focusing only on big claims: frequency concerns underwriters more than one large loss for most SMBs.
- Hiding past losses: omissions discovered during underwriting can jeopardize coverage or trust.
- Not challenging outdated reserves: stale reserves can linger for years if not questioned.

FAQ
What is a loss run?
A loss run is a claims report from your insurance carrier showing all claims for a policy or account over a specified period, including claim amounts, status, and reserves. It is the primary document underwriters use to assess your claims experience.
How far back should loss runs go?
For renewal planning, request at least 5 years of loss history. Many underwriting models use a 3-year lookback, but 5 years provides fuller context and helps identify longer-term patterns or one-time anomalies.
Can correcting errors on loss runs actually lower premium?
It can help. Correcting inflated reserves, removing duplicate entries, or closing stale claims improves your loss ratio presentation, which may lead to better pricing or expanded carrier appetite. Results vary by market and carrier.
What if I have no losses but premium still increased?
Carriers also consider broader market factors (reinsurance costs, inflation, catastrophic losses) and your specific risk profile (payroll growth, new operations, location). Clean loss runs help, but they don’t control external rate pressure.
Should I share loss runs with competitors before quoting?
Yes, with strategic guardrails. Share a summarized version showing key figures and corrective actions. Full reports can go to finalists. Transparency often improves quote quality by reducing underwriting uncertainty.
